GEORGE w. PENNISTON, OE NORTH vERNON, INDIANA.

Specification forming part of Letters Patent No. ll7,053, dated April14, 1857.

To all whom it may concern:

Be it known that I, GEORGE W. PENNrsroN,

of North Vernon, Jennings county, Indiana,

` compressing cotton-bales.

In'the accompanying drawings, Figure 1 is a top view of my machine. Fig.2 is a per spective View (on a larger scale) of the self acting latchand its accessories.

a a are a series of levers (two on each side) attached at one end to theplunger d, jointed in the center to the short arms b, (which are threein number on each side,)a1'1d forming therewith a duplex toggle-joint,which is operated in either direction by the advancing or retraction ofthe plunger d by means of the reversible differential capstan c, thedifferential pulley k, and the pulleys ZJ l Z.

r'is an arm attached to the plunger d, which,

when the plunger arrives at the end of its stroke7 impelling forward therod e, withdraws the key f from confining the button y, at which timethe pressure tfrom within, operating against the button g, causes thelatch h to fly `back and the side doors, m m, to open automatically, forthe cording of the bale, after which a slight reverse motion of thecapstan c retracts the plunger and liberates the bale.

The dotted lines n represent a groove in the bottom ofthe press-box, inwhich ts a corresponding tongue on the bottom of the plunger,- thusdirecting the plunger in a straight for ward direction and protectingthe doors from any side pressure therefrom.

My improvements will enable the operator of the press to make any numberof bales of a given size, and uniform, so that they may be stowed withincertain dimensions. By varying the length of the bar e the doors may bereleased whenever the plunger arrives at the desired point to make thebale the size required.

I do not claim the duplex toggle-joint nor the mode of operating itdescribed; but

"What l do claim, and desire to secure by Letters Patent, is-

The traversing bar e, in connection with the arm t of the plunger, forthepnrpose of retracting the key f to release the doors when the plungerarrives at the proper point to make the bale being pressed the sizerequired.

In testimony of which invention I hereunto set my hand.
